is there any way to check asynchronously whether stdin contain data to read?

Hello All!

I want to ask you whether there is any way to check asynchronously
whether stdin contain data to read. I tried all operations to read
stdin, but it looks all that operations are blocking.

Thanks in advance,

Yes, all standard C library I/O operations are blocking. Normally there is
some OS-specific way to do what you ask, but you should ask about that on
group(s) dedicated to the system(s) of interest.

HTH,
